ResumoIn Colorado, there has been considerable interest in the feasibility of utilizing fire-killed trees as a source of biomass fuel for the production of heat energy. However, the effect of time that a fire-killed tree stands dead has on the fuel value of its wood was uncertain. This research focused on the measurement of higher heating values for wood from standing dead ponderosa pine trees killed in forest fires along the Colorado Front Range in 1996, 2000, and 2002 compared to wood from live ponderosa pine trees. The hypothesis that there was no difference between the higher heating value of living trees and fire-killed trees was accepted. The hypothesis that there were no difference between the higher heating value of trees killed by fire in 1996, 2000, and 2002 was also accepted. However, the recoverable heat of combustion was higher for trees that had been dead longer, as a result of lower wood MC.
